.\ l 1 claim.

This invention'relate's to safety razors and more particularly to a means wherebythe blade, while heldin the razor, can be sharpened quickly, the sharpening element being a part of the 5 razor and located normally where it will not interfere with the shaving operation.

A further object is to provide a structure of this character which is simple and compact in construction, formed of few parts, will not readily get out of order, and can be easily actuated for the purpose of sharpening the blade.

With the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being. understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawing the preferred forms of the invention have been shown.

In said drawing Figure l is a front elevation of the razor.

Figure 2 is a section on line 2 2, Figure 1, the sharpening element being shown in engagement with the cutting edg'e of the blade.

Figure 3 is a view similar to Figure 2 showing the sharpening element retracted and the cutting edge of the bladein operative position.

Figure 4 is a perspective View of the sharpening element.

Figure 5 is a section through a portion of the handle of a[ modified form of razor showing the same utilized as a housing for a shaving brush.

Referring to the iigures by' characters of reference I designates a handle which can be of any desired shape and size. In the structure shown in Figures l, 2 and 3 this handle is solid but it is to be understood that, if desired, the handle can be made hollow as shown at 2 in Figure 5, the recess aiiixed in the handle opening through one end thereof but being normally closed by a removable cap 4.- In this handle is slidably mounted the base '5 of a shaving brush E, there being a knob 1 connected to the base and slidable along a slot 8 in the handle. Thus after the cap 4 has been removed, knob I can be shifted in one direction to bring the brush in position ,-,0 where it can be used for shaving purposes. While the brush is thus extended it can be secured in any manner desired.r For example knob 'I can be located at one end of an elongated scr-ew 9 eX- tending through base 5. Thus when the knob is rotated it will bind upon the handle 2 and hold the base fin be moved. The .handle'fineitherf'forrn ofthe device-is formed with a slotted head I0 having' a flat end plate II preferably made integral therewith and formed along one edge with spaced guard teeth or lingers I2 such as commonly used in safety razor constructions. This plate II has a slot I3 opening into the slot I4 in head I0, and slidably mounted on plate il is a at sharpening element I5 which can be a thin metal plate or a plate of glass or any other suitable sharpening material from-which depends an ear I5 adapted to slide Within slot I3. This ear has an elongated slot I which receives a pin I1 extending through 'ang/ position to weigh n ymight an operating wheel I8. The wheel is mounted for rotation in slot I4 on a cross pin I9. It is to be understood that ear I5 can be forked, as shown in Figure l so as to straddle the Wheel I8 and thus be held against lateral movement relative thereto.

The wheel is formed in its periphery vnth notches and these notched portions of the wheel project outwardly in opposite directions respectively from the slot I4 so that a iinger of the hand of the user can be employed to vmove the wheel back and forth about its axis of rotation, thereby transmitting motion through pin I'I and ear I5 to the sharpening'element I5 which thus will be reciprocated upon the'outer surface of the plate II.

Plate II is provided at one edge with a flange 2I which can carry an integral supporting ledge 22 shaped to support the enlarged or thickened back portion A of alrazor blade B. One or more spring clips 23 can be suitably joined to the nange 2 I these clips being so shaped and proportioned as to overlie and exert a downward pressure upon the back A of blade B. Thus the cutting edge C of the blade will be held normally pressed against the guard fingers I2 at a point where it will operate efciently to shave a person. Under thesev conditions the sharpening element I5 will be located between the flange 2| and the cutting edge portion of the blade, as

- shown in Figure 3.

While the parts are located as in Figure 3` the razor can be used in the same manner as an ordinary safety razor. However should it be desired to sharpen the blade B, all that is necessary is 'for the user to rotate Wheel lI8 in one direction so as to thrust the sharpening elem-ent I5 forwardly between the cutting edge of blade B and the guard fingers I2. This has been shown in Figure 2. While the sharpening element is thus located the Wheel can be rotated back and forth, thereby causing said element to reciprocate and as it is constantly contacted by the cutting edge portion C of the blade, said edge Will be quickly sharpened. After the cutting edge has been treated in this manner, the sharpening element l5 is shifted back to the position shown in Figure 3 and the razor can then be used as before.

The razor blade can be placed in or removed from position by sliding it longitudinally between the ledge 22 and the clip or clips 23.

What is claimed is:

A safety razor including a handle, a longitudinally slotted head thereon, an end plate integral with the head and having a slot, guard fingers integral with and extending Vfrom one edge of the plate, said plate having a flat supporting" surface, a pivot device Xedly mounted inthe head and extending across the slot therein, a wheel mounted for back and forth rotation on said pivot device within the slot in the head and extending into close proximity to and lying in the same plane with vthe slot in the p late, said wheel having opposed portions extending outwardly from the slots for engagement by a finger of the hand grasping the handle for actuation thereby, a flat sharpening element slidably mounted on the plate and normally positioned back from but above the plane of the guard iingers, a blade-supporting ledge integral with the plate, yielding means cooperating with said ledge for gripping a razor blade and holding, the sharpened edge of said blade normally in contact with the plate close to the guard ngers and in the path of the sharpening element, and means extending from the sharpening element and mounted for right line movement in the slot in the plate for actuationfby the wheel when rotated back and forth, said means and the Wheel cooperating to reciprocate said sharpening element between the lcutting edge of the held blade and the guard fingers and to Withdraw said element from engagement With the cutting edge into position between the slotted plate and the held blade.
